Production Process of Enameled Wire |
||
| 1 | Annealing Oven | The bare wire is annealed to achieve the necessary softness of copper |
| 2 | Enamel Applicator | The enamel is applied in many single layers by the applicator (up to 30) to ensure good adhesion of the enamel to the copper conductor and ensure a suitable insulation property. |
| 3 | Curing Oven | In the oven, solvents are driven out of the enamel by heat |
| 4 | Lubrication Application | Lubrication is for the finished enamel surface to obtain good slidability |
| 5 | Laser O.D. Control | The laser will continuously control the outer diameter |
| 6 | Tension Control | Control the winding tension closely |
| 7 | Spooling | The wire is evenly spooled on the supply spool with consistent tension |
| 8 | Monitor | Continuous production data to the operator provided by the Monitor |
